a.34 to 38 inches
b.30 to 34 inches
c.36 to 42 inches
d.42 to 48 inches
Explanation
Handrail top height must be between 34 and 38 inches measured vertically from the nosing line. 30 to 34 inches is too low; 36 to 42 and 42 to 48 inches are too high and overlap guard heights rather than handrail heights.
